If you specifically aren't wanting to use the kit chassis for mecanum applications as Billfred mentioned you can also use the Nanotubes, which still have the Toughbox Nano embedded in them:
It has been a couple years but we used this with pretty good success in 2013 and 2014 when I was with 167, running the Vex Pro mecanum wheels cantilevered off the nanotubes. Makes a very compact robot, the only tricky part is figuring out bumper mounts.
